I have been listening to "Engines" for several years, and I do everything I can to hear it every day. Dr.Lienhard's ability to clearly show us how science, invention, art, literature, history, and our present all intermingle to form the world we are in today, as well as our future, always fascinates me. Dr. Lienhard has the same vision as many of the figures he so sincerely admires. Listen to just one of these episodes, and you will be not only hooked, but educated. Bravo, Dr. Lienhard! Bravo!
